CHARLES COLLE, OF LILLE, FRANCE, ASSIGNOR TO HECTOR LA'HOUSSE & CO., OFSAME PLACE.

GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 403,253, dated May 14,1889.

Application filed October 1, 1888.v Serial No. 286,849. (No model.)Patented in Belgium .Tune 8, 1888, No. 82,112, and in England June 18,1888l No. 8,905.

.To aZZ whom t may concern.-

Beit known that I, CHARLES COLLE, en-

gineer, (of the firm of Hector Lahousse da Co.,)

a citizen of the French Republic, and a resident of Lille, in theRepublic of France, have invented certain new and useful Improvements inElectric Batteries, (for which I have obtained Letters Patent inBelgium, No.

82,112, dated June 8, 1888, and in Great Brit- 1o ain, No. 8,905, datedJune 18, 1888,) of which the following is a specification.

This invention relates to an improved twoliquid battery, in which anovel liquid is employed to act on the zinc in the porous vessel I5witha view of obtaining, by the aid of improved arrangements of theparts situated eX- ternally to the said porous vessel, a very constantcurrent of great power at a relatively low cost.

And in order that my said invention may be fully understood, I shall nowproceed more particularly to describe the same, and for that purposeshall refer to the several figures on the annexed sheets of drawings,the same let- 2 5 ters of reference indicating corresponding parts inall the figures.

Figure 1 of the accompanying drawings represents a battery according tothis invention in vertical section. Fig. 2 is an end elevation Fig. 3 isa plan. Fig. 4t represents a perspective view of the top of the battery,showing the arrangement of the parts; and Fig. 5 represents an elementwith two carbons for a large battery.

The battery according to this invention is made with an external vesselof a material proof against the action of the concentrated nitric acidwhich it contains and inclosing a porous vessel, B, containing a specialliquid 4o for acting on the Zinc, C. The space between the two vesselsis filled with granular carbon, D, packed around electrodes E ofretort-carbon, forming the positive pole, the whole being covered by alayer of pitch, H, or other suitable material, through which the porousvessel, the carbons, and two glass tubes, F F, project. The tube F isemployed for introducin g the concentrated nitric acid, while the airescapes by the tube F. After this operation both the tubes arehermetically sealed, 5o to prevent any escape of hyponitric vapors.

The action on the zinc is obtained by means of a solution composed ofabout thirty-live parts, by weight, (say thirty-live grams,) ofbisulphate of mercury and thirty-live parts, by weight, (thirty-fivegrams) of concentrated nitric acid in about one thousand part-s, byweight, (one liter,) of water. In preparing this solution the bisulphatemust be mixed with three hundred parts (thirty centiliters) of water, inthe first instance shaking or agitating it until the solution is of thecolor of yelk of eggs, and then continuing the agitation while thenitric acid is being poured in and until the liquid becomes clear. Thesolution thus prepared is poured into the porous vessel, in the interiorof which the zinc is afterward placed, being allowed to rest upon acollar, G, of porcelain or other inoXidizable material, which also actsas a cover for the said porous vessel. The battery thus constituted isused in the same Way as an ordinary battery, over which it possesses thefollowing advantages, namely:

First. The current is very regular and not liable to sudden accessionsof force. The intensity of the current is about two volts and thequantity from about six and a half to seven ampres for a minimum periodof action of about sixty hours.

Second. The zinc is equally acted on at all points, is consumed veryslowly and with great regularity, and never requires taking out of theliquid.

Third. The residues are zinc salts and free mercury. These products arevaluable, and may be collected either for the purpose of beingregenerated or for sale.- In either case their commercial value is animportant set off against the cost of working the battery.

Fourth. The battery requires but little attention to keep it in workingorder compared to a Leclanch battery, for example.

Fifth. Owing to the small proportion of the salt of mercury employed inone charge, and also owing to the long duration of each charge,

In a two-liquid battery with a porous cup, the combination of a solutionof bisulphate of mercury and concentrated nitric acid in suitableproportions and a zinc plate in one cell, with granular-retort carbonand ordinary carbons and nitric acid in the other celhsubstantially asherein set forth.

In testimony that I claim the foregoing as my invention I have Signedlnynanle, in presence of two witnesses, this 18th day of September,188%.
